I feel your pain....lolThis new edition of the Navigation/Infotainment system is "dog dodo". It is cumbersome, not at all intuitive, and a potential car wreck waiting to happen. IMO, you should be able to access, operate,and select your preferances with a miniscule amount of time with your eyes of the road. Even with the use of the mouse, when you are driving in freeway traffic, dicking around with the mouse and trying to line up a particular target while trying to keep your eyes on traffic is not my idea of a "User Friendly" package. It reminds me of the old saw, "A Zebra is a horse that was designed by a committee". Whom ever Lexus chose for this design must have been told to use the concept of the New Coke Campaign. Paul I don't know if the OP got his question answered, but in case he didn't, there is a way to change the default nav screen from coming up each time you start the car (under settings, turn auto screen off). Interestingly, in the US market, it's impossible to configure your system to have the "home" screen come up when you start your car. Why call it "home" if you can't default to that screen? As for the 3IS nav/infotainment system, let's just say that the Lexus halo is tarnished. There are at least three threads in the Club Lexus forum that document persistent problems with the nav and audio system that Lexus has yet to address successfully. It's the weak link in an otherwise well executed car.

I think so. It's not a very expensive option and you can push the car much harder in turns in Sport+ mode. It also firms up the ride--not night and day, but a discernible difference. Also, all of the positive press for the car (Car and Driver and Road and Track) came from F-Sport models.
